Dark Matter

You point at a creature within range. A mass of dark matter forms from your fingertip and shoots itself at the target. Make a Spell attack roll. On a hit, a creature suffers 1D10 Necrotic damage. 

At Higher levels: The damage dice is increased by 1D10 at 5th (2D10), 11th (3D10) and 17th (4D10) level.
